What to do when your Mazda Miata starts from cold?
This normally occurs within two minutes with the engine started from cold, and can be observed by a noticeable drop in rpm at idle. With the engine warmed up disconnect the pig tail wire of the O2 sensor from the main engine wire harness. Repeatedly and quickly apply large amount of throttle. If throttle response is normal, replace the O2 sensor.
What causes acceleration issues on a Mazda Miata?
From prior experience I know issues with the MAF (Mass Air Flow) can cause SERIOUS issues with acceleration. [Note: I was at Autobahn Country Club near Joliet, IL a few years ago and ran across the FIA rumble strips pretty aggressively on corner exit and jarred the piping connecting the air inlet to the throttle body loose.
How to fix a Mazda that stalls at stop?
Remove the air hose from the throttle body. Disconnect the throttle body connector. Remove the throttle body from the intake manifold, with the water hose connected. Clean the throttle body on the air hose side using a soft, clean shop cloth, sprayed with engine cleaner (Mazda recommends their P/N 000-77-A86).
What should the fuel pressure be on a Mazda Miata?
Connect a fuel pressure gauge (About $60 at your local auto parts store) to the high pressure fuel line. The high pressure fuel line is the rearmost of the two metal lines (passenger side of engine), pictured. Pictured below is the pressure I read off the fuel pressure gauge. The Haynes manual states between 32-38 psi is normal, at idle.

What kind of car is a 1995 Miata?
The troubleshooting I’ve done here is specific to a 1.8L 1995 Miata, you may apply what I’ve done here for your application. This may have been a problem that has been stewing for awhile but became such an issue at Hallett this past summer that I had to solve it.
What to do about bogging on a Mazda Miata?
With the engine warmed up disconnect the pig tail wire of the O2 sensor from the main engine wire harness. Repeatedly and quickly apply large amount of throttle. If throttle response is normal, replace the O2 sensor. For me, I still had the “bogging” and misfires.
When did the Mazda Miata win Car of the Year?
It also won “Car of the Year” from Wheels Magazine in 1989, 2005, and 2016 (the first years of the NA, NC, and ND generations), and it’s made Car and Driver’s annual “10 Best” list 17 times. But if you’re like us, this sort of greatness is never enough.

What’s the throttle response on a Mazda Miata?
This is somewhat of a common problem for this generation of Miata. My issues were primarily below 4000 rpm, and after the engine had warmed up. Throttle response was seemingly normal across all rpm ranges with a cold engine. With a warm engine and above 4000 rpm the acceleration seemed normal.
Is the 1991 Mazda NA Miata in good condition?
Gorgeous 1-Owner Crystal White 1991 Mazda NA Miata with the factory painted to match Hardtop we sold through our Mazda store 30 years ago. It was the subject of a complete, trim off paint-job at our certified body shop. It was not damaged, but the paint was not in good condition and warranted this.
What should the temperature be on a Miata?
At about 210°-220°F, it will sit at the 12 oclock position. At 230°F, you can see the gauge start to move to the 1/2 oclock position. Many here will probably never see it move, but if it does, be sure you stop and cool the car.
What does warm engine mean on Mazda Miata?
With a warm engine and above 4000 rpm the acceleration seemed normal. A warm engine is indicated by the O2 sensor sensing a warm exhaust manifold. The troubleshooting I’ve done here is specific to a 1.8L 1995 Miata, you may apply what I’ve done here for your application.
Why is my Mazda Miata bogging at 4000 rpm?

Where is the pig tail wire on a Mazda Miata?
There is a pig tail wire leading from the O2 sensor and connected at the main engine wire harness near the upper part of the rear of the engine by the ignition coil. Wait for the engine to warm up. This normally occurs within two minutes with the engine started from cold, and can be observed by a noticeable drop in rpm at idle.
What should the idle RPM be on a Miata?
Factory spec for the Miata specifies standard timing as 10° before top dead center (10° BTDC) ±1° at idle speed(850 rpm). If your timing is advanced more than this, you may experience pinging under some conditions. Dirty spark plugs Metallic burr in cylinder

Why does my car Jerk when I Turn on the gas?
A Faulty Fuel Line Fuel lines are responsible for the flow of gas throughout the engine system. If it is faulty or if there’s a leak somewhere, a pressure is lost, thus causing the car to jerk. Faulty fuel lines can even cause a fire in your engine or worse, an explosion.
Why does my car jerk at low speeds?
Car jerks when accelerating at low speeds is not something rare. If you have driven a stick shift car before or if your car has a manual transmission, you are sure have experienced the car jerk followed by the engine stalling.
What to do when your car jerks when accelerating?
Below is the steps to practice but you should ask your driving teacher for further understand if needed: Press the clutch pedal down to the floor. Move the stick into first gear and ease onto the gas pedal while at the same time slowly releasing the clutch pedal. Make sure to perform this transition smoothly, or else the car will jerk really fast.
Why does my car Jerk when I press the gas pedal?
Your catalytic converter have the function of regulating the emissions that come out of your car. At times, the rich mixtures of air and fuel flowing through your catalytic converter can clog up. This clogging stuff can lead to a jerking or stuttering motion when you press the gas pedal.
Why does my car hesitate when I hit the gas?
Whenever you took off from rest, the harder you jumped on the gas pedal the deeper and longer the hesitation. At higher revs the engine seemed to be a slightly down on power. Thinking the problem was related to vacuum, fuel delivery and improper fuel air ratio, I spent a lot of time looking at things in this area, but how completely wrong I was.
How to take care of an MX 5 Miata?
Do not race the engine. Do not maintain one constant speed, either slow or fast, for a long period of time. Do not drive constantly at full-throttle or high engine rpm for extended periods of time. Avoid unnecessary hard stops. Avoid full-throttle starts. Basically, just go out and drive it normally and have fun!
What does the Mazda MX 5 look like?
The MX-5 has an annoyingly happy face. It looks like a really stupid but overly-confident person who’s too thick to contemplate their own existence, so just bounds around the place like a giddy child on too many Smarties.

Are there any problems with my 1995 Mazda Miata?
Talk about Miata problems and share solutions with other owners here. My 1995 Miata had only 3900 miles on it when I bought it in ’97. I drive it only about 3000 miles each year and store it over the winter. About 4 years ago the engine developed a hiccup, especially at slow speeds. Also, there’s a strong exhaust smell in the trunk.
